(Cl. 108-74) This invention relates.generally to the baling of trash and more particularly to an improvedportable apparatus for facilitating baling of trash directly at trashsites.

Conventional trash equipment for forming bales of trash is usuallylocated at a permanent site and the trash brought to the balingapparatus from various locations in trucks. in baling the trash,relatively complex equipment has been employed to compress the same intoa given sized bale for easy storage or subsequent re-use by paperproduct mills and the like.

With the above in mind, it is a primary object of this invention toprovide a novel portable apparatus for baling trash, in which theapparatus may be driven directly to a trash site and trash loadedtherein and compressed into suitable bales of standard size.

More particularly, it is an object to provide an improved portableapparatus for baling trash particularly adaptable to waste paper,cardboard, and the like to form compressed bales at a trash site whichmay subsequently be loaded onto commercial vehicles for transportationto any desired location to the end that the immediate disposal of trashis greatly facilitated.

Still another important object is to provide a portable apparatus forbaling trash meeting the foregoing objects which is rugged inconstruction, economical to operate,

and may easily be transported to any desired site by conventionalcommercial vehicles.

Briefly, these and further objects and advantages of this invention areattained by providing a basic frame structure having wheels tofacilitate the portability of the structure. A trash receiving enclosureis mounted on the frame structure and includes compressing means withinthe enclosure so that trash received within the enclosure may bedispensed therefrom in compressed form and in a regulation sized bale.

The invention thus contemplates the steps of loading trash into anenclosure; moistening the trash; compressing the trash to a smallervolume in the enclosure; loading additional trash into the enclosure;moistening the additional trash; compressing the additional trashagainst the first mentioned trash; repeating the last mentioned threesteps a plurality of times until a compressed bale of trash of givenvolume is formed; and then unloading the compressed bale of trash fromthe enclosure. The .roistening step serves to bind the material togetherand cause it to adhere in a given compressed shape cor responding to acommercial bale.

The preferred apparatus includes an enclosure and compressing meanswithin the enclosure as described. Preferably, hydraulic means areemployed for effecting the compressing operation. The enclosure itselfincludes a lower front gate and upper rear gate and incorporates aplatform adapted to be raised between lower and upper positions toeffect the compressing operation. By this arrangement, trash may readilybe loaded into the lower front gate from a trash site without having toraise the trash beyond a minimum distance. On the other hand, when thesame has been compressed by raising of the platform to squeeze the trashagainst the ceiling of the enclosure, the completed bale is disposed ata higher level and when removed through the rear gate is in a properposition for reception directly onto a commercial vehicle for subsequenttransportation.

"ice

Various features of novelty in the portable apparatus include thearrangement of hydraulic units for actuating the system and theprovision of unique means for enabling the trash to be compressedagainst the ceiling of the enclosure as well as unique means forfacilitating the unloading of a completed bale.

The foregoing will be better understood by now referring to a preferredembodiment of the invention as disclosed in the accompanying drawings,in which:

FIGURE 1 is an overall perspective view of the portable apparatus forbaling trash in accordance with the invention;

FIGURE 2 is a fragmentary cross sectional front view taken generally inthe direction of the arrows 2-2 of FIGURE 1;

FlGURE 3 is a side view partly in cross section taken generally in thedirection of the arrow 3 of FIGURE 1;

FIGURE 4 is an enlarged fragmentary cross section of a portion of thestructure of FIGURE 3 enclosed within the circular arrow 1; and

FIGURE 5 is a schematic diagram illustrating the hydraulic circuits foroperating the various components of the structure illustrated in FIGURES13.

Referring first to the lower portion of FIGURE 1, there is illustrated abasic frame structure 1% having wheels 11 for rendering the structureportable. As shown, the frame structure supports a trash receivingenclosure 12 generally of box shape. This enclosure includes front andrear walls 13 and 14, sidewalls 15 and 16, a lower floor or bottom wall17 and a top wall or ceiling 18.

A portion of the front wall 13 includes a front gate 1h mounted forswinging movement at 19' along the lower front longitudinal edge of thebottom wall 17. The rear wall 14 in turn includes a rear gate 20 whichis mounted for swinging movement along the upper rear longitudinal edgeof the top wall 18 as at 2%. Included within the enclosure is a platform21.

With particular reference to FIGURE 2, there are provided platformraising and lowering means for the platform 21 in the form of a pair ofhydraulic cylinders 22 and 23 secured to the frame structure on oppositesides of the enclosure 12. As shown, these cylinders include piston rods24 and 25 coupled at their upper ends to pull rods 26 and 27. The lowerends of the pull rods in turn connect to opposite sides of the platform21. The sidewalls 15 and is, as best shown in FIGURE 1, includeelongated slotted open portions for accommodating the upper ends of thepull rods 26 and 27. Guiding means for the upper ends of the piston rods24 and 25 in the form of angle irons such as indicated at 23 and 29 areprovided and extend a considerable distance above the top wall 18 of theenclosure. The arrangement is such that actuation of the hydrauliccylinders 22 and 23 will serve to raise the platform 21 from a lowerposition juxtaposed the front gate 19 to an upper position juxtaposedthe rear gate 29.

Referring to the side cross sectional view of FIGURE 3, the front gate19 is arranged to be actuated by a hydraulic cylinder 30 disposedbeneath the frame structure 16. This cylinder 30 is mounted for swingingmovement and includes a front projecting piston rod 31 coupled to asuitable push bar 32 in turn rigidly secured to the front gate 19.Outward movement of the piston rod 31 will serve to close the front gate18 whereas retracting movement thereof will serve to open this gate.

Similarly, the rear gate 29 is arranged to be actuated by a hydrauliccylinder 33 disposed along the top wall 18 of the enclosure. As shown inboth FIGURES 1 and 3, this cylinder 33 actuates the rear gate 29 throughthe medium of a flexible cable 34 secured to a rigid bar 35 extendingnormally from the plane of the rear gate 29. The cable then passes abouta pulley 36 and is secured to the front of a piston rod 37 projectingfrom the clylin der 33. Hydraulic actuation of the cylinder 33 will thusI 13-. This front wall 13-includesa key hole type slot 40 through whichthe piston'rod 39 for the cylinder 38 projects. Actuation of thehydrauliccylinder 38 will extend the piston rod 39 to push a bale 41 oftrash from the up per portion of the enclosure through the rear gate 20.t

In accordance with one feature of this'invention, the

upper interior'corner portions ofthe rear gate 20 include rigid bars 42extending normally from the plane of the line 2will be connected to theline 55 so that high pressure passes into the line 54 to the upper endsof the cylinders to lower the pistons, fluid from the lower ends of thecylinders passing-through line 52 to line 55.

As also, shown in FIGURE 5, the front gate cylinder 30 is'arranged to'beoperated-by hydraulicfiuid pressure in the line 52 through a branch-line56 passing through a hand valve '57. When the piston from the cylinder30 is extended as "by high pressure passing through the valve, the front7 gate will be closed. This action may-take place substantiallysimultaneously as the lift cylinders commence operation; that is,whenhigh pressure is on the 7 line 52 from the four-way valveSl. On theother hand,

gate so that when the gate is swung outwardly, the bars a 42 will swingdownwardly to bear against the upper surface ofthe bal'e41 and tilt thesame to facilitate its removal from the enclosure;

' As shown in FIGURE 3-, the frame It! also serves to support a'sourceof hydraulic fluid 43 cooperating with a hydraulic pump 43' forsupplying hydraulic fluid under pressureto the various cylinders. Bythis arrangement,

the unit is entirely self-contained.

In accordance with a furtherfeature of the apparatus, there is providedmeans for moistening trash received through the front gate 19. Thismeans takes the form of a header pipe 44 also shown in FIGURE 1 arrangedto receive water under pressure from a suitable pump (not shown)connected to a water tank 45 disposed beneath the front gate structure19 as shown in FIGURE 3. The same drive for the hydraulic pump 43' maybe used'to drive the water pump for pumping spray water from tank whenit is desired to retract the cylinders and open the front gatepreparatory to receiving further trash, high pressure on the line 53 will:be passed through a branch line 57 to the otherend of the cylinder 30to retract the piston rod therein; Return fiuid from the right hand endof the cylinder will then pass thrdugh thevalve 57, and line 52, to thereturn line 55. c v t The rear gate cylinder 33 shown in the lowerleft-jhand earner of FIGURES in turn is arranged to be actuated 45. Bymoistening trash received through the front gate,

preparatory to its being raisedby the platform 21 to form a bale, thetrash will tend to. adhere together and bind more easily. J

As will be evident from the front view of FIGURE 2 by high pressurefluid'from thepump 43' passing through a branch line 59 and a'hand valve60. This fluid enters a four-way valve 61 similar to the valve 51 whichis capable of providing high pressure on either one of two output lines62 or 63. When pressure is applied to output line 62, the piston for thecylinder 33 is extended to open the rear'gate. When high pressure isprovided on the line 63, the piston inthe cylinder 33 will retractpermitting therear gate to close. t r

Cooperating with this same four-way valve 61 is the cylinder 38 forejecting the bale as described in conjunction withFIGURE 3. Thiscylinder may be operated to push the bale from the upper portion of theenclosure at the same time that thejreargate cylinder 33 is operated,and towards this end, there is provided a branch line 64 passing througha hand valve 65 to the righthand end of the cylinder 38 V v a V when thereartgate is retracted or. closed, the fluid passing through the line 63also passes to the left end The wall is shaped such that the element '46may swing from a horizontal position generally upwardly towards avertical position to lie substantially co-planar with the wall.

by a stop structure 48 abutting the rear end of the element 21, itwillpush past the elements 46 swinging them upwardly as indicated indotted lines in FIGURE '4; 'When the trash has passed the elements, theywill falltto their horizontal positions by gravity and thus engageunderthe However, the element 46 is locked against down-' ward swingingmovement beyond a horizontal position J of the cylinder 38 to retractthe to the formation of another bale.

piston rod 39 preparatory From the foregoing description, the operationof the overall system willbe evident. Initially, and with referenoe toFIGURE 3, the rear gate 20 is closed and the front gate 16 swung open byoperation of the hydraulic cylinder 30. Further, thetplatform 21 is inits lowermost trash that has been raised so that theplatform 21 may belowered preparatory to receiving additional trash.

Referring now to FIGURE 5,rthere is illustrated a 7 simple schematicdiagram of the interconnections between 1 I 60 the various cylindersdescribed in conjunction with FIG? URES 1 -3. As shown, the source 43and pump 43' pro vide hydraulic fluid under pressure along a first line49 to a hand operated valve 50. From the valve 50, the fluid underpressure passes to a four-way valve 51. Depending upon the position ofthis four-way valve'51, hydraulic fluid under pressure can be'provided,on output. line"52 or 53. When provided on o'utputli'ne 52, thefluidwill pass to the lower ends of the cylinders 22 and 23 to raise thepistons. therein, fluid above these; pistons then passing 'out the line54. The fluid in the line 54 then passes down line 53 which functions asareturn line when the. fourposition as shown in. dotted lines in FIGURE3. Under 7 such conditions, trash directly from a trash site readily maybe loaded onto the platform 21 and this job may be carried out veryeasily since the platform level is relatively low as compared with therest of the structure. When a certain'amount of trash has been insertedthrough the front gate, thefront gate 19 is swung closed by actuation ofthe hydraulic cylinder 30." Simultaneously, water from the sprayheaderpipe 44 may be ejected to moisten the trash. i

Y Asrthe gate 19 is being closed, the lift cylindersZZ and 23 may beactuated through the high pressure line 52 from the four-way valve 51described in FIGURE 5 to raise'the platformZL 'Ihe trash will thus becompressed againstthe top wall 18 of the enclosure, and as the trashpasses the various elements 46 pivoted to thefront and ,rear walls,theseelements will be retracted and then by gravityffall to horizontalpositions 'to engage under the way valve is in the position described,the returnfluid passing through a line to the reservoir 43.

If the four-way'valve is moved in the opposite-direction, high pressurewill be provided on the line 53, and the edges of thefcompres'sed trash.7

'After the trash has beeninitially compressed-,the platform is loweredwiththerear: gate 20 held closed and the front gate19 again' opened toreceive furthertrash. This further trash is then raisedand'compressediagainst the trashalready being held in the, upper portionof; the en-' closure by the elements 46. The additional trash-suppliedto the -platform-isrmoistened-by water from the header pipe 44 so thatit will adheretogether and be compressed into a solid mass with thefirst trash already disposed in the upper portion of the enclosure.

The foregoing process may be repeated a plurality of times until arelatively large bale is formed in the upper portion of the enclosure.When it appears that further compression is not feasible because of themass of trash present in the upper end of the enclosure, the rear gatemay be actuated and at the same time the cylinder 38 operated to extendthe piston 39 and urge the bale 41 shown in FIGURE 3 from the upperportion of the enclosure. In this connection, opening of the rear gate20 will cause the bars 42 to engage the upper top portions of the bale41 to tilt the same as illustrated and thus facilitate its removal fromthe enclosure.

Since the rear gate portion of the enclosure is at a higher level thanthe front gate portion, commercial type trucks having rear platforms maybe positioned substantially level with the rear of the machine of FIGURE3 so that the bale may be received directly thereon. Thus, an importantfeature of this invention resides in the fact that during thecompression operation, the mass of trash is actually raised to a higherlevel to facilitate loading onto commercial type trucks.

After the bale 41 has been removed from the upper end of the enclosureas illustrated in FIGURE 3, the rear gate is closed and the platform 21lowered and the front gate 19 opened preparatory to receiving furthertrash. The various plurality of compression and moistening steps arerepeated until another bale is formed and this latter bale is thenejected in the manner described for the bale 41.

From the foregoing description, it will thus be evident that the presentinvention has provided a greatly improved portable type apparatus forbaling trash. While only certain components in the apparatus have beenshown and described in accordance with one embodiment of applicantsinvention, it will be evident that equivalent steps and components couldbe substituted without departing from the scope and spirit of thisinvention. The improved portable apparatus for baling trash is thereforenot to be thought of as limited to the exact embodiment set forth merelyfor illustrative purposes.
